摘要： Synthetic transmit aperture is provided for three-dimensional ultrasound imaging. A transducer may have separate transmit and receive elements. Broad beams are transmitted, allowing fewer transmit elements and/or more rapid scanning. A multidimensional receive array generates data in response to sequential transmissions, such as transmissions from different angles. The data is combined to increase resolution. A transducer array with offset transmit elements for forming a transmit line source may be used.

摘要： A single chip transducer apparatus that includes on-chip electronic circuitry which, when connected properly to a two-dimensional matrix of ultrasonic transducer elements, provides enough information to an external imaging system to form three-dimensional images of the subject of interest. In a preferred embodiment, the circuitry provides an amplifier for each transducer element, and then conditions the output of the amplifier in several ways. In one embodiment of the invention, the elements' analog voltages are stored in a sample and hold circuit, and time multiplexed into a high speed line driver that sends many elements data down the interconnect to the system's high speed Analog to Digital converters. In another embodiment, the gain of the amplifiers can be controlled in time to provide aperture translation and time based expansion for translating and focusing image slices in the elevation direction.

摘要： A capacitive microfabricated ultrasonic transducer with control of elevation phase through alternating bias polarity is disclosed. Such control of elevation phase results in simple ultrasonic probes with excellent slice thickness attributes. Furthermore, tight spatial variation of phase results in an effective way to achieve transmit aperture and apodization control. Further still, such capacitive microfabricated ultrasonic transducers can achieve elevation focus without the need of a lossy mechanical lens.

摘要： The present invention provides an transducer and a method of making the same. The transducer is comprised of a plurality of transducer cells, and conductive interconnects between the cells. Each transducer cell contains a bottom electrode formed on a layer of insulator material, a lower insulating film portion formed over the bottom electrode, a middle insulating film portion that includes an air/vacuum void region, and an upper insulating film portion that includes a top electrode formed within a portion of the upper insulating film portion. A first layer of interconnects electrically connect the bottom electrodes of each transducer cell and a second layer of interconnects electrically connect the top electrodes of each transducer cell. The top and bottom layers of interconnects are patterned to avoid overlap between them, thus reducing the parasitic capacitance. Further, as noted, the top electrode is preferably formed within the upper insulating film portion, closer to the air/vacuum void than to the top surface of the insulating film, to increase the electric field for a given voltage. Still furthermore, the electrodes within each transducer cell are preferably formed to have dimensions that are smaller than the overall surface area of the membrane that they excite.
